Patented Aug. 4, 1931 UNITED STATES PATENT 'OFFICE PHILIP N. BRAUN, OF SYRACUSE, NEW YORK, ASSIGNOR TO THE PROSPERITY COM- PANY INC., OF SYRACUSE, NEW YORK, A CORPORATION OF NEW YORK MOTHPROOFING MEANS FOR PRE'SSING MACHINES Application filed June 12,.

This invention relates to pressing machines, as garment andlaundry presses, particularly to machines of the type set forth in my pending application, Sr. No. 363,178 filed May 15, 1929 having means for treat- 5 ing the work with a verminor mot-h proofing agent by passing a current of air containing the agent by suction or blowing or both through or against the work, and it has for its object means for creating a closed system for the air when laden with the vermin or moth proofing agent so that said agent is not wasted by being blown into the outer air and further so that the operator is not subject to discomfort or annoyance because of the agent being blown out into the air.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawin'gsin which like characters designate corresponding parts in all the views. 7

This invention comprises, generally, a con- 1929. Serial No. 370,402.

duit system for passing a current of air through the work being operated upon by a pressing machine or between the pressing elements of a pressing machine, a branch conduit having a chamber therein for a vermin or moth proofing or a similar agent and operator-operated valve means for cutting the branch conduit in and out of the air cona head 1 movable toward and from a buck,

2, the buck being suitably mounted on a frame 4 and the head beingsupported and actuated in any suitable manner. shown as carried at the front end of a forwardly and rearwardly extending lever 5 pivoted between its ends at 6 to the frame, and this lever is actuated by any suitable mechanism.

It is thought that a description of this actuating mechanism is unnecessary, especially as many forms of actuating mechanism, either foot or power operated, are well known in this art.

Each of the pressing elements is formed with an internal chamber 7 or 8 for receiving a heating medium as steam. Each pressing element is also formed with a lengthwise channel 9 or 10 which is covered by a perfora-ted plate 11 or 12, and with a foraminous pressing plate 13 or 14 spaced apart from the plate 11 or 12 to form asteam or air distributing chamber 15 or 16.

Steam is supplied to the chambers 7 and 8 in any well known manner.

Steam is supplied to the channel 9 of the head 1 in order to bedistributed through the chamber 15 and plate 13 through a valve located in the casing 17 mounted on the head and operated by a handle 18, the casing communicating with the chamber 7. through ""1 It is here foraminous plate 13, and operation of the 7 edal 25 will result in steam being projected through the foraminous plate 14 of the buck 2 The current of air for carrying the vermin proofing agent is also distributed through the channels 9, 10 and the foraminous plates 7 13, 14 through a pipe or conduit 26 opening into the channel 9 of the head 1 and a pipe or conduit 27 opening into the channel 10 of the buck 2.

Normally'closed valves 28, 29 are located in the pipes 26 and 27 respectively. Thevalve 28 is operated from the handle 18 through suitable motion transmitting mechanism, as a link 30, connected to the link 18 and to one arm of an angle lever 31, the other arm of which is connected to thestem 32 of the valve 28. A spring 33 normally holds the valve 28 closed. Thejvalve 29 is operated from a pedal 34 pivoted to the base'of the frame, the pedal being connected by a link 35 to the stem 36 of the valve 29. The stem 36 extends lengthwise of the conduit 27. A'spring 37 normally holds the valve 29 closed.

The'air conduit system is here shown arranged-to blow air from the head through the work on the buck and suck the airsuitable means and is preferably created by a blower located in a casing 38 and actuated by an electric motor located in a casing 39.

The motor is' normally idle or cut out of its energizing circuit, and is connected in the circuit by a switch, not shown, located in a casing 40, the switch being operated by a .lever 41 pivoted on the casing 40 and connected to a link 42 which is pivotedto the pedal 34 to be actuated thereby. The link 42 also actuates a reversing valve to be 'hereinafter referred to. The operation of the lever 34 is against the action of a returning.

' spring. 43.

The pedal lever 34 when initially actuated moves far enough to actuate the lever 41 to close the switch without moving the reversing valve piston 48, hereinafter de-- scribed, far enough to reverse it. The spring 43 permits further movement of the pedal 43 to reverse the valve 48 while holding the switch closed through the lever 41.

As shown in Figure 7, the outlet 44 of the blower is connected by pipes 45 and 46 to the casing 47 of a reversing valve, which valve also includes a rotary piston 48. The casing 47 is connected to the pipe 26 in the head so that the air is blown through the head and the foraminousplate' 13 thereofthrough the work, and at the same time the air is sucked through the foraminous plate 14'of the buck through the pipe 27 to the reversing valve casing 47 to the opposite side of the piston 48 which is in its full line position, thence through pipe 50, through a condenser or moisture removlng device 51,

valves 52, 53 connected by a pipe 54 through ipes '55 and- 56 to the intake 57 of the lower. Upon reversing the piston 48, to the dotted line position, of the reversing valve by depressing the pedal 34 to its .full extent, the air will pass from the outlet 44 of the blower through the pipe 45 to the reversing valve casing .47, the piston 48 being now inthe position indicated by dotted lines, so that the air will pass through the pipe 27 and blow through the foraminous plate 14- of the buck through .the work thereon and be drawn by suction through the foraminous plate 13 ofjthe head through the pipe 26 line po sition, through the pipe .50, condensing device 51, valves 52, 53 and connecting pipe 54, pipes 55, 56 to the intake of the blower.

58 and 59 designate the branch conduits in which there is a container 49 having vermin or moth proofing or similar agent therein,

these conduits 58, 59 being connected to the casings of the valves 52, 53. The valves 52, 53 are provided with \passages 60 and 61 which normally are so arranged as to cut out the branch vermin proofing conduit and which are operable to cause said passages 60,

61 to connect the pipes 50, 56 and the pipes pipe 56.

These valves 52 and 53 are'here shown as rotary valves located in suitable casings and as operated by rock arms 62 and 63 which .are .connected by a link 64, the rock arms bei'n connected to an operating rod 65 extending to the front of the machine and having a handle 66 at its front end. Obvious- 1y, upon the pushing of the handle 66, the

valves 52 and53 will be moved out of their normal position and by pulling on the handle they will be restored to their original position.

I is for the purpose of removing the moisture from the air, that is, drying or refreshing the air after it is passed through the work between the pressing elements, and therefore, constitutes an inlet for a new or fresh supply of air. 1

This condensing device may be of any suitable form, size and construction.

' Iii-operation, when the valves 52 and 53 are in their normal position shown in Figure 7 the air circulates through the system and is I'BfI'QSlIW'l during each cycle of movement by the condensing device 51. IVhen the valves 52, are moved to out in the vermin or moth proofing branch, the air circulates through a closed system so that practically none of the vermin proofing agent is lost ordischarged into the outer air.

In Figure 8, when the vermin or moth proofing branch is cut out of the circuit, the outer air is taken into the system, and the air is blown only either from the head or the buck and not sucked through either the head or the buck, and when the moth proofing branch is cut into the system, the inlet of air to the closed.

In Figure 8, the air passes through the intake 51 to the passage 61 of the valve 53 .through the pipe 56' to the pipe 56 to the inlet 57 of the blower, out through the outlet 44 of the blower, pipe to the reversing valve casing 47 on one side of the piston 48 when in full line position, thence out through the pipe 26 through the head against the work thereon. N o suction is created through the pipe 27, reversing valve casing 47 and pipe because the passage 6050f the valve 52 is out of alinement with the pipe 50, thus air is blown only through the head.

By operating the piston 18 of the reversing valve 47* into the dotted line position,

1 with the valves 52 and 53 in the same position, air will be blown from the discharge outlet 44 of the blower through the pipe 45 to the reversing valve casing 47 at one side of the piston 48 which is now in dotted line position, thence cut out through the pipe 27 and through the buck 2 and the work thereon. No suction will be created through the head 1 and the pipe 26, reversing valve casing 47,pipe 5O because the passage of the valve 52 is out. of alinement with the pipe 50.

' Upon operating the valves 52, 53 to bring the passages 60 and 61 into opera tive position to cut in the branches 58 and 59 'of the vermin proofing branch, the intake 51 will be closed so that now with the reversing valve piston -18 in its full line system from the outer'air is 'closed circuit, from the discharge end 44 of the blower through the pipe 45, reversing valve casing 47 above the piston 48 into full line position through the pipe 26" and through the head and by suction, through the work on the buck and through the buck to pipe 27*, reversing valve casing 47' below the piston 18 in full line position, pipe 50*,

valve passage (50 to the vermin proofing branch 58, 49, 59 passage 61 of the valve 53, and pipe 56 to the intake end of the blower. i I

By reversing the reversing valve 47 to move into dotted line position, the current of air will pass in the reverse direction and blow through the buck 2 and the work thereon and suck through the head 1.

In Figure 9, the conduit system is arranged to suck air through the buck or the head in accordance with the position of the piston 18 of the reversing valve, when the vermin proofing branch 58, 49 and 59" is cut out of the system. v

In Figure 9,- the valves 52 and 53 are shown in their position assumed when the vermin proofing branch 58, 59 and 49 is cut in the system and thesystem closed to the outer air. The air current passes from the blower outlet 44 pipe 70, passage 61* of the valve 53 pipe 71 to the reversing valve casing 47* to the upper side of the piston 48 in full line position through pipe 26, through the head, and is sucked through the buck pipe 27 to the reversing valve 47* below the piston 48* in full line position through pipe 50 passage 60 of the valve 52", vermin proofing branch 58, 49*, 59*, passage 67 of the valve casing 52 and pipe 56" to the intake end 57 of the blower. Upon reversing the reversing valve piston 48 into dotted line position, the air will be blown through the buck and sucked through the head.

If the valve 52 is rotated into position so that the passa e 60 establishes communication betweent e pipes 500 and 56 and the valve 53* is rotated into position so that the passage 72 establishes connection between pipe 70 outlet pipe 51, then the vermin proofingattachment branch is cut out of the system. With the valves 52 and 53 in this position air will be sucked through the head pipe 26 reversing valve 47 and with the piston 48 in dotted line position through the pipe 50 and branch 500 thereof, passage 60 of the valve 52", pipe 56 to the intake 57 b of the blower 38 through the blower outlet 44, pipe 70, passage 72 of the valve 5? out through the outlet 51 into the outer air.

By operating the reversing valve piston 48 to full line position, air will be sucked through the buck pipe'27 to the reversing valve casing 47 to the lower side of the 1.
